Question

我在对话框的Imagview中打开了一个弹出菜单。单击菜单项时，我有一个语音朗读功能，它的倒数从10到1。我想在单击菜单项后关闭菜单。我尝试了popup.dismiss（）和closeOptionsMenu（）但没有运气。请帮帮我。

Imageview counter = (Imageview) findViewById(R.id.imgview);
counter.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        PopupMenu countMenu = new PopupMenu(MainActivity.this,counter);
        countMenu.getMenuInflater().inflate(R.menu.counter_menu, 
         countMenu.getMenu());

countMenu.setOnMenuItemClickListener(new 
PopupMenu.OnMenuItemClickListener() {

            @Override
            public boolean onMenuItemClick(final MenuItem menuItem) {
String selectedCount = menuItem.getTitle().toString();
countMenu.dismiss();
//Tried closeOptionsMenu(); too here but doesn't work

if(selectedCount.equals("Some String")
{
//TTS counter from 10 to 0
 return true;
}
countMenu.show();

Answer 1

返回 true 将不在您的 if 语句之内。您已将 return 语句置于 if 内语句，这就是计数结束后关闭的原因。

示例代码：

 countMenu.dismiss();

 return true;

 if(selectedCount.equals("Some String")
 {
 //TTS counter from 10 to 0
 }

从对话框中退出弹出菜单
